and there it is.
The second-largest hill made of bedrock in the United States. The rock is about 1,825 feet above sea level. It's an exfoliation dome with layers that peel away over time.
Batholith:
Enchanted Rock is the exposed part of a much larger batholith, a massive underground mass of cooled magma.
Formation:
The granite was formed from magma that cooled and crystallized deep within the Earth's crust.
Exfoliation Dome:
Enchanted Rock is an exfoliation dome, meaning it has layers that peel away due to stress relief from the removal of overlying rock and soil.
Erosion:
Over time, the surface rock and soil have eroded, exposing the granite dome.
